ZERO VOLTAGE TRANSCEIVER OPERATING IN TERAHERTZ BAND

摘要

The present invention relates to a zero voltage transceiver operating in the terahertz (THz) band. The zero voltage transceiver operating in the THz band according to the present invention includes: a substrate; a transmitter Tx disposed on the substrate, transmitting THz waves and not using a bias voltage; a receiver Rx disposed at a certain interval from the transmitter Tx and detecting the THz waves, wherein the transmitter Tx includes a metal wire that has a certain thickness and line width, and the receiver Rx includes a second active layer disposed on the substrate; and a photoconductive antenna disposed on the second active layer. Through such a configuration, the zero voltage transceiver operating in the THz band according to the present invention does not use a bias voltage and thus remarkably improves a signal to noise ratio, may use a laser pulse having low peak power, and may be safely used even when it is applied to medical diagnostic equipment to be used on the human body.
